Synthetic aperture radar (SAR) systems have the unique advantage of all-time and all-weather observation. In the past decade or so, with the continuous announcement of multi-mode, multi-angle, multi-dimension, wide-swath, high-resolution, and multi-static SAR observation technologies, SAR observation has been in the "new generation" stage. This paper first introduces the development of the observation capability of the new generation SAR, including how to realize the wide-swath, multi-temporal,
